Do-it-yourself caterpillars for a single-axle tractor Neva
What are the types of caterpillar system?
In one case, the module with caterpillars is made in the form of an axis. From below it is supplemented with four rollers. And already with the help of rollers, the necessary mechanical stress of the caterpillar belt is formed. Left and right is a pair of gear. Finding into the gaps of caterpillars, they stretch them and allow the device to move.
Moving gears horizontally occurs due to a special framework. It is attached to the bolts. One of the sides of the shaft equipped with gears is complemented by gear gear. By a special chain, it broadcasts the effort to the tracked block. In the running ribbon, V-shaped parts are built, the sharp face of which looks along the motoblock.
There is another actuator. On the device of the tracked ribbon, it does not reflect. Only wheels are replaced with a large gear that is attached to the axis. At the bottom of the frame is equipped with eight rollers. The purpose of using these rollers is to keep the belt taut and ensure smooth movement.
Installation
The uniqueness of caterpillar attachments lies in the fact that their installation instead of the basic, wheel drive in a matter of minutes turns an ordinary single-axle tractor into an efficient towing vehicle, all-terrain vehicle or snowmobile. Such modernization is most relevant for equipment belonging to the category of small-sized agricultural units with a shaft with a diameter of 30 mm. The caterpillar module can be purchased ready-made or assembled independently. To implement the second option on the World Wide Web, you can easily find drawings and video instructions for assembly and installation.
High-quality purchased and well-made do-it-yourself devices are characterized by increased strength and durability. Do not forget about the ease of installation, operation and maintenance. Installation of a purchased platform of any configuration and complexity does not require special knowledge and technical means. It will be enough basic skills and a minimum set of tools. Installing homemade units has a number of nuances. It should be borne in mind that a platform that is too high shifts the center of gravity of the entire machine, which in itself negatively affects its stability. As a result, the risk of the walk-behind tractor tipping over off-road and when performing maneuvers is significantly increased. To increase the stability in the process of installing the caterpillars, it takes above to place an additional axis.
In addition, it is necessary to take into account the width of the axes. Experienced owners advise if necessary to increase the wheelbase. If there is no differential, you can use a rotary extension as an effective alternative. This triangular device will positively affect the maneuverability of the caterpillar motor. When choosing, acquiring, manufacturing and installing a crawler drive, it should be taken into account that such an upgrade is not relevant for air-cooled models. This is due to the excessive load on the power unit.
How to make a caterpillar module for a walk-behind tractor with your own hands?
This block usually works by installing an additional pair of wheels and connecting them with a caterpillar track.
Here are the most common options for such models:
In this case, they all turn out to be a fixed width. Often they have to be brought to the desired size by hand. This laborious procedure. However, the end result is a solid model.
This is a very simple option when several grousers are connected with one tape. This design is easy to manufacture, but not reliable enough. Since the connecting tape often breaks.
This is a very cheap version of the caterpillars, and anyone can make them. After all, consumables are almost always at hand.
This option is the most popular. It can be applied at any time of the year. This type of caterpillar module is extremely easy to manufacture, but the compounds are not very reliable.
The option should be chosen based on what functions the caterpillar module will perform, and what is the power of your walk-behind tractor.
For small capacities, simple structures can be used, they can withstand standard loads. But for more powerful units, you should use more durable models.

Which option to choose?
Options are not so much, but everything depends on your imagination.
- Conveyor belt roller chain. The simplest and most common option. Universal, such caterpillars will not let go in winter, nor in summer, neither in the fall. The minus of the received copies is the low reliability of the connection.
Online Auction Buy. Caterpillar C-10 Diesel Engine. Will it Run or is it Junk?
- Car tires. Labor-intensive option. The resulting fixed-width samples often have to be modified. Caterpillars are durable.
- Grouser belts. Easy to manufacture. Caterpillars are universal. Minus. low reliability.
- Chains Metal plates. Advantages In the low cost of materials. iron or steel plates can be found almost every farm, like old chains. Make such caterpillars can and beginner.
The choice of the optimal option depends on the power of your motoblock: the more powerful, the more serious can be caterpillars. Easy motoblocks are better to select simple options from a standard agricultural conveyor belt.
Increasing the strength of the caterpillars made at home. this is a question that worrying owners. The first option of the caterpillars will need to be flashing around the edges so that the tape does not fail. over, the tape is also fastened by stitching. this is an unreliable method. Take the hinges. so the strength of the connection will be higher.
Tires are initially selected for the required size of the caterpillar, so their contour is not broken, such options are durable and reliable. When choosing tires, it is better to focus on samples for tractors or trucks.
Instances obtained by attaching belts to lugs are connected together with riveting or screws. such a connection is strong and reliable, so no additional measures are required.
The fourth option is reinforced by additional welding of chain links, which have become the junction of the chain into a ring.
Step by step instructions for making
To make a caterpillar mechanism for a walk-behind tractor with your own hands, in addition to the materials used, you will need certain tools: an angle grinder, and sometimes a drill, a shoe knife and a set of screwdrivers, bolts, nuts and wrenches, a welding machine, wire, chains and a sanding belt. Of course, drawings will also be necessary, which are easy to find on the Internet in the public domain.
If home-made caterpillars are made from car tires, then the first thing the tires are freed from the sides to the state of the running tape. tracks for tracks. It is easier to do this with a well-sharpened knife, for example, designed to work with boots. The adjustment process turns out to be lengthy, but it will be possible to speed it up if you periodically coat the blade with soapy substance.
It is more convenient to cut the sidewalls of tires with an electric jigsaw with fine teeth. At the next stage, the underside of the tire is also corrected: excess layers are removed from it. This should be done when the tape is too dense inside. Such a caterpillar attachment from automotive parts turns out to be quite durable, since the tire is initially closed, which means that the tracks will be more difficult to damage during operation. Unfortunately, the available width of the tire will not give the user the opportunity to use a large surface. However, some craftsmen solve this problem by using several tires.
The simplest caterpillar module can be made from a conveyor belt and roller chains. First, depending on how powerful the engine is, the required thickness of the tape used is selected. Next comes the processing of the edges, which can begin to shag and, because of this, fail earlier. For this, a fishing line is used in increments of ten millimeters. The processed edges are then sewn into a ring, with a special hinge, or simply along the end parts.
Despite some primitiveness of the mechanism, it will serve for a very long time. It is important to add that the thickness of the tape must exceed seven millimeters, otherwise the device will not be able to withstand the required loads. A gap of eight to ten millimeters is considered optimal.
Crawler module will be able to make belts if they have a wedge-shaped profile. It is best to connect the parts with a grouser, which is fixed on the straps with screws or rivets. Another common solution is to construct caterpillars from chains of equal size. Such a universal part, as a rule, is available in large quantities in any home workshop, so this method is also economical. To make caterpillars, you have to take a pair of equal chains and unclench their extreme links.
Now two chains can be connected to one contour, links to hold back and for reliability everything is welded. For greater strength, the chain can be copped again with primers, which, by the way, are also simply made from undergraduate materials. metal sheets of the required thickness. In general, this item may be not only steel, but wooden and even plastic. In the latter case, wooden bars or plastic tubes are used as it. Which material will be most suitable can be determined depending on the purpose of using the walk-behind tractor.
In the event that the cargo expected for transportation does not differ in large weight, the lugs should be made of plastic. The same applies to moving devices equipped with weak motors. When a single-axle tractor is planned to be used as a tractor, and it has a fairly powerful engine, steel parts should be preferred.
Sometimes home-made caterpillars are strengthened with pipes, which are interconnected by welding. Parts in this case are made of metal and have a rectangular cross section. At the same time, it is recommended to remove the drive shafts from the Oka, and take the splined part from the Buran. The equipment must be equipped with brakes that are mounted on the front shafts. This addition allows you to get a device with maximum capabilities.
It is worth mentioning that in order to convert a conventional single-axle tractor into a tracked tractor on the go, you first have to put two additional wheels on it, one on each side. As a result, a four-wheeled design should be on which caterpillars are already worn. Some DIYers prefer to make these extra wheels removable instead of welding on new mounts. This can be done if you attach the wheels to the axle using a flexible or rigid gear. It is impossible not to mention that it is not necessary to make caterpillars on your own. an equally economical solution would be to use parts from old equipment, for example, “Buran”.
Homemade caterpillars for walk-behind tractor
Many owners of walk-behind tractors note that the potential for improving the functionality of this technique is very, very high. In addition to the possibility of aggregation with all kinds of attachments, which allows mechanizing most of the work, it is possible to increase the throughput of the unit on viscous soil and on snow in winter. This allows a caterpillar drive for a walk-behind tractor.
